I am having some trouble with browsing OPC tags from an AB 1400.
All I can see are the first tags within the areas of the PLC and nothing else.
Any other tags referenced outside the first address come back with a NULL and Unknown tag quality
I have restarted the Gateway and OPC module and cant seem to find a solution.
Never seen this before. I am using v7.9.1. Has anyone come across this before, or know of a fix?
